The idle roller is spaced apart from the unwinding roller so that the roll of material can be supported on the idle roller and the unwinding roller. The motor is in mechanical communication with the unwinding roller and is configured to axially rotate the unwinding roller.

Abstract: A method for purifying cumene may include splitting an alkylation reaction product into a first portion and a second portion; feeding the first portion as mostly a liquid into a benzene column; at least partially vaporizing the second portion in a heater; feeding the at least partially vaporized second portion into the benzene column. A method for purifying cumene may also include the steps of providing a benzene column and a cumene column; directing a liquid side draw from the benzene column to the cumene column, the liquid side draw being a liquid substantially free of DIPB; returning a benzene enriched vapor from the cumene column to the benzene column using an overhead line, the benzene enriched vapor having a higher concentration of benzene than the liquid side draw; and drawing purified cumene from the cumene column.

Abstract: A supply roll stand for loading first and second supply rolls each including a core and dispensing material therefrom. The supply roll stand broadly comprises a frame, a lift support, an unwind assembly, and a transfer support. The lift support receives the first supply roll and raises the first supply roll. The unwind assembly unwinds the first supply roll as the lift support raises the first supply roll. The transfer support receives the first supply roll so that the first supply roll is transferred from the lift support. The lift support receives the second supply roll after the first supply roll is transferred to the transfer support. The transfer support dispatches the core of the first supply roll when the first supply roll is depleted of material. The unwind assembly unwinds the second supply roll when the first supply roll is depleted of material.

Abstract: A steam cracking unit including one or more electric resistance heating tubes electrically connected to a current source to generate heat via electrical resistance heating. Each resistance heating tube may include two or more tube sections. Each tube section may be independently supplied with a current. A controller may be configured to adjust the application of the current to one or more tube sections to control the electrical resistance heating of the one or more resistance heating tubes. In examples, the one or more electric heating tubes may be used as preheating tubes, cracking tubes, or both.

Abstract: A first stream containing 1,3-butadiene, C4 acetylenes, and optionally C3 hydrocarbons, is mixed with a portion of the liquid recycle stream from a C4 acetylene hydrogenation reactor containing hydrogenated C4 acetylenes and a molecular hydrogen-containing stream, the resulting mixed stream is then fed to a C4 acetylene hydrogenation reactor to selectively hydrogenate the C4 acetylenes in the crude butadiene stream without appreciable 1,3-butadiene conversion.

Abstract: Disclosed is a method for preventing, delaying or reversing age-associated inflammation, by administering to a patient in need thereof a therapeutically effective amount of at least one reverse transcriptase inhibitor (RTI).

Abstract: A syngas reforming exchanger reactor design is described. The reforming exchanger has a head, a shell, and a tubesheet secured a tube bundle. The tubesheet is bolted to the shell, after which the head is bolted to the shell. A seal is configured between the tubesheet and components of the shell. Another seal is configured between components of the head and the tubesheet. In the reformer exchanger design, those seals are maintained under bolted pressure via the bolting of both the tubesheet and the head to the shell. This design improves the integrity of sealing, thereby preventing escape of hot reformed gases from the reformer exchanger reactor during operation.

Abstract: A magnetic gradiometer can be used in systems or methods for nondestructive testing, even when the material being tested is weakly magnetic. The magnetic gradiometer can include a printed circuit board (PCB) comprising a first end and a second end separated by a base length; an excitation coil encircling at least a portion of the PCB and configured to deliver an alternating current (AC) to generate an excitation magnetic field; and a differential sensor. The differential sensor can include a reference magnetic tunneling junction in magnetic vortex state (vortex MTJ) sensor array at the first end to generate a voltage based on the excitation magnetic field; and a signal vortex MTJ sensor array at the second end to generate another voltage based on the excitation magnetic field due to a composition of the measurement target. The second end of the PCB can be oriented towards the measurement target.

Abstract: This dual-compartment liver co-culture system exposes target microtissue to metabolites, allowing for evaluating toxicity using a standard multi-well plate for high throughput analysis. Discovery scientists can rapidly select lead compounds with desirable metabolic profiles, while safety scientists can determine the safety of drugs, pesticides, and environmental chemicals. This platform is allometrically scalable, so it can mimic the natural size differences between healthy organs and, with the liver, produce sufficient quantities of metabolites. The device is simple to use and designed for immediate in vitro pathology assessment using confocal microscopy, transcriptomics, and proteomics.

The present invention provides a stable analog of CN2097.

Abstract: A two stage system for extraction of oil from whole citrus fruit is provided. The first stage is known in the art and includes a first plurality of toothed rollers which convey citrus as the teeth penetrate and rupture oil glands. The oil passes into a first water pan. A novel second stage uses a second plurality of toothed rollers to continue the penetration and rupturing of oil glands. The second plurality of rollers are positioned in an isolated second pan to partially submerge the citrus. A middle phase liquor with extremely low oil concentration is transferred into said second pan to initiate desorption of oil from the citrus. The desorption technique in one embodiment increases yield by 4% or more. This technique is expected to increase yield even more as the recovery by the first stage is reduced.

Abstract: A reactor system and method for catalytic dehydrogenation of saturated C3-C6 hydrocarbons within a reactor placed within a reactor disengager, where the reactor is open at the bottom thereof and open to the disengager, and the exit riser from the reactor is not hard coupled to at least one downstream cyclone. This configuration permits controlling the amount of catalyst within the reactor by varying the level of catalyst in the reactor disengager outside the reactor and permits controlling total catalyst hold-up and/or weight hourly space velocity (WHSV) independently from catalyst flow from the catalyst regenerator.
